This was told by my woodwork teacher in 1968 so bear in mind some of the terms may not be politicaly correct. Please be aware that no offense is intended!
An American Indian Chief had 3 wives. The first he held in high regard and so he sat her on a hide made of Buffalo. The second he also held in high esteem and sat her on the skin of a mountain lion. The third, and youngest, he loved dearly and had a hippopotomus hide specialy imported for her.
The years passed and his three wives bore him a fine son each. The two elder wives however became bitter and jelous of the younger. When their boys were old enough they told them to go and murder the child of the youngest.
One dark night they crept from their tents to commit the foul deed but the son of the youngest wife woke and fought of his two half brothers bravely and so survived. Just proving that...
The son of the squaw on the hippopotomus is equal to the sons of the squaws on the other two hides.
